Summary:
With traditional way of meteorological early warning issued not timely response to sudden limitations of meteorological disasters. Network will need to promptly send wireless LED systems according to the China meteorological administration published the meteorological disaster warning signal distribution and transmission methods, schools, airports, and tourist attractions and densely populated urban area and public management unit, the use of the electronic display unit must be set or the distribution of meteorological early warning signal. The meteorological disaster warning signal distribution and transmission method "requirement, meteorological offices and stations subordinate to the competent meteorological departments at various levels shall make full use of radio, television, electronic display device, such as early warning signals to the community in a timely manner. In minority nationality areas the warning signal in addition to the use of Chinese language and text, also should use the local minority language. In addition, it also requires the local people's governments at various levels to strengthen early warning signal of infrastructure construction, establish a clear and effective early warning information release and communication channels, to expand the coverage of early warning information.
Traditional main meteorological information through television, newspapers, radio, SMS, Internet and other ways to release, the release way need to have a media transfer process, there will be some time delay, the public also want to receive information through these media channels, the arrival rate will have a certain degree of loss, which affects the effectiveness of the meteorological information release. Therefore, the traditional way of meteorological early warning issued cannot cope with the sudden meteorological disasters in a timely manner.
Meteorological early warning information release platform can directly through the LED screen in the first time, a warning horn, TV meteorological early warning information release to the public, do not need to transit through the media, to effectively shorten delivery time delay, improve the arrival rate, thus improve the effectiveness of the meteorological early warning information release.
System topology:
In the platform, all kinds of terminal will be warning information content through the LED, TV (no matter what users currently are watching TV, directly to the early warning information by GTV superimposed on the TV screen), loudspeakers broadcast.
System design is shown below:
System advantage
Our company is the industry's first launch of embedded GPRS module the full range of LED control system and the information release system, manufacturers. GTV is our original products, with appearance and invention patent.
Day letter each wireless meteorological early warning information release platform development contains the complete database management platform, terminal services communication center, a web-based operating software, product development is completed at the end of 2010, and through the internal test, in a number of provincial meteorological users open network operation.
System not only meet the commonly used the weather forecast, the actual weather information and major meteorological disaster early warning information release, at the same time, using the system to provide special information slots mechanism, can also satisfy the real-time release of relevant government administrative functions of the important government affairs and public emergency early warning information, scope of fast release for important information to all parts of the city, the streets and homes, achieve the purpose of notification and propaganda.
System features:
Wireless LED meteorological early warning information release system adopts B/S (easy to use, easy to upgrade maintenance) architecture pattern, the main interface (including the Web server) issued by the information, information release platform server (database), FTP server information, weather information data sources (including the meteorological warning information server, weather forecast information, weather, rolling information server, etc.), terminal equipment (LED control card and monitor, early warning loudspeakers, GTV, TV), such as five parts. Has the following features:
1) network scale
Meteorological early warning information release system adopts the model of point to multi-point network, integrated meteorological early warning information release system through the GPRS network architecture model, all data storage and service center server to facilitate daily system maintenance. Client software anytime, anywhere where there is Internet access can be realized data management operations.
2) efficient real-time transmission performance
The wireless data transmission part of the system using UDP screen to visual and auditory synchronous broadcasting.
3) stability reliability
The particularity of meteorological early warning information release system using the environment, must ensure that the system is relatively stable and reliable. One is the reliability of the system, with stable and reliable operating system and servers as comprehensive meteorological early warning information release platform carrier, comprehensive meteorological early warning information release platform have permissions operation function, can guarantee the reliable operation of the system from the application; Second, a variety of patterns and channels of information release model, solved the weather information to the last kilometer "problem in the countryside, farmers can greatly improve the ability of disaster prevention and mitigation, and bring huge agricultural economic benefits. After completion of the system platform construction, can also be used for other emergencies to government departments, major disaster early warning, policy propaganda and information release, business information, etc.
